storcon_cli tenant-describe: include tenant-wide information in output (

#9899)

Before this PR, the storcon_cli didn't have a way to show the
tenant-wide information of the TenantDescribeResponse.

Sadly, the `Serialize` impl for the tenant config doesn't skip on
`None`, so, the output becomes a bit bloated.
Maybe we can use `skip_serializing_if(Option::is_none)` in the future.
=> #9983
